Steven Nott tells the inquiry that he accidentally discovered a way to hack
into voicemails and that journalists at the Daily Mirror threatened him with
legal action after he tried to make it public.

Giving evidence at the Leveson Inquiry into media ethics and phone hacking, Steven Nott, a delivery driver from Wales, told the inquiry he had tried to warn telephone companies, the police, the Home Office and the Security Services that mobile phones were vulnerable to hacking.

He also told The Sun and Oonagh Blackman, contacted a reporter called Oona Blackman at the Daily Mirror, who would later become the paper's political editor.

He claims she said she and her colleagues tried the system out on celebrities around London – but after being told there would be a celebrity story, she then said no story would appear.

He says in his witness statement Ms Blackman "threatened him with court action" if he told anyone about the information he had told her. He was paid £100.
